WHEEL.

Specification of Letters Patent.

Patented Jan. 21', 1919.

Application led January 8, 1918. Serial No. 210,923.

To all whom t may concern.'

Be it known that we, LEONARD NILsoN and HAROLD NlLsON, citizens of the United States, residents of Wayzata, county of Hennepin, State. of Minnesota, have invented certain new and useful Improvements in Wheels, of which the following is a specification.

' The object of our invention is to provide a wheel designed particularly for traction machines of simple, economical construction and one which can be effectively used in soft ground for traction urposes, or on a highway in moving the mac line from place to lace. y

ther objects of the invention will ap- Vpear from the following detailed descrip- The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a side elevation of the wheel embodying our invention, dn,n

Fig. 2 is a vertical sectional view ofilrhe same,

Fig. 3 is an edge view with the' tread of the wheel partially broken away, showing'a modified construction.

In the drawing, 2 represents an axle, 3 a vertical stud or bolt on which the casting 4 of the wheel spindle is journaled. 6 is a hub mounted on thespindle 5 and having seats 7 thereon at each end for a series of spokes 8, made preferably of flat metal of suitable width and gage. These seats have shoulders 9 thereon against which the inner ends ofthe spokes are butted, a suitable means,'such as rivets 10, securing the inner ends of the spokes to the hub. 11 represents the sections composing the rimV of the wheel, ,each made preferably of angle bar bent into circular form with one flange formin' thetread of the wheel and the other ange projecting outwardly from the center of the tread and forming a rib extending entirely around the ywheel. These flanges may vary 1n width, according to thesize of the wheels and the weight thereon. The outer ends of the spokes extend between the flanges 12 and are secured Athereto by rivets 13 which pass through the flanges 'togetherl and through the abutting ends of the spokes, thereby riveting them and the flanges firmly The load on the wheel will exert a `longitudinal thrust on the spokes, which will be transmitted to the shoulders 9 and prevent shearing of the rivets securing the spokes to the/hubs and as the spokes flare or diverge near their outer ends, the load on'the wheels 11y which might tend to shear the rivets at the outer ends of the spokes will be resisted by the engagement of the rim sections with the diverging portions of the spokes. When the machineis running on hard ground, the flanges of the rim sections at thecenter of the .wheel will carry ter of the wheel at all points across theA tread, thf` outer ends of the'spokes being flush substantially with such surface.

This whjfeel may bemad'e in various sizes and the width of the flanges of the rim sections may be varied to meet the different requirements of the wheel.

' We claim as our invention:

1. A wheel comprising a hub, a rim therefor composed of angle bar sections bent to a circular form and having their vertical flanges placed back to back at the center of the wheel, the other flanges of' said angle bar sections forming the tread of' the wheel, said vertical flanges projecting outwardly beyond said trend and forming u narrow surface on which the wheel may roll on hard ground, and spoke 'members having their outer portions projectingbetween said vertical flanges and secured thereto and diverg- `ing within said rim sections and Ahaving their-'inner portions secured to the ends of said hub.

2. A wheel comprising a hub, a rim therefor composed of angle bar sections bent to a circular forni and having their vertical flanges placed back to back at the center of the wheel, the horizontal flanges of said angle bar sections forming the tread of the g l memes wheel, said vertical ilanges projecting mtin@ their inner endsl secured to the ends of Wardly beyond said tread and forming a said4 hub. y

narrow surface on which the wheel may In witness whereof, we have hereunto set 10 roll on'hard ground, and a series of spokes our hands this 7th day of December, 1917.
